Concept Search - What can I type?

For a concept search, you can enter phrases, sentences, or full paragraphs in English. For example, copy and paste the abstract of a patent application or paragraphs from an article.

Concept search eliminates the need for complex Boolean syntax to inform retrieval. Our Semantic Gist engine uses advanced cognitive semantic analysis to extract the meaning of data. This reduces the chances of missing valuable information, that may result from traditional keyword searching.

Abstract

When a credit transaction is to be entered in a transaction recording device, actuation of a charge key indicates that the transaction is to be identified by use of a credit card. An interlock switch is actuated to prevent a total cycle of the machine until the contacts of switch 2 are opened indicating the presence of a credit card. Credit card tray 3 receives the card on central depressed card bed 4 causing interposer 5 to be pivoted to a longitudinally aligned position in slot 6. With the credit card inserted, the moving of tray 3 in the direction of arrow 8 to the operating position causes interposer 5 to engage the inclined cam surface 9 moving slide 10 upward to engage switch 2 and removing the interlock permitting the entry to be completed.

Imprinter Card Tray

When a credit transaction is to be entered in a transaction recording device,
actuation of a charge key indicates that the transaction is to be identified by use
of a credit card. An interlock switch is actuated to prevent a total cycle of the
machine until the contacts of switch 2 are opened indicating the presence of a
credit card. Credit card tray 3 receives the card on central depressed card bed 4
causing interposer 5 to be pivoted to a longitudinally aligned position in slot 6.
With the credit card inserted, the moving of tray 3 in the direction of arrow 8 to
the operating position causes interposer 5 to engage the inclined cam surface 9
moving slide 10 upward to engage switch 2 and removing the interlock permitting
the entry to be completed. In the absence of a credit card, interposer 5 fails to
engage slide 10 and the interlocked condition remains. During each cycle,
channel cam 12 rotates causing reciprocation of slide 13 connected to it by pin
14 which projects into channel 15. When a total cycle occurs, with a credit card
present, slide 16 is moved in the direction of arrow 23 terminating latching
engagement with slide 17. Spring 18 then urges slide 17 upward to drive tab 20
of link 19 into slot 21 causing reciprocation of link 19 in unison with slide 13 to
effect actuation of an imprinting mechanism.
